  Zusatzpatent zum Hauptpatent     Nr.   <B>107855.</B>    Verfahren zur Darstellung eines Wollfarbstoffes der     Safraninreihe.       Im     Ilauptpatent    ist ein Verfahren zur  Darstellung eines     Wollfarbstoffes    der     Safranin-          reihe    beschrieben, gemäss welchem man     Iso-          rosindulin-1        -12-disulfosäure    von der Formel  
EMI0001.0010     
    in Gegenwart von Sauerstoff oder Sauerstoff  abgebenden Mitteln mit     1-4-Diamiiiobenzol-          2-sLilfo,%ätire    kondensiert.  



  Ein Farbstoff, der die gleichen guten  Eigenschaften zeigt, wie der im Hauptpatent  beschriebene, wird nun erhalten, wenn man die       Isorosindtilin-1   <B>-</B>     12-disulfosäure        voi-    der Formel  
EMI0001.0016     
    die aus     S-Sulfophenyl-2-Y)aphtylamin        und        1-          Dimethylamiiio-4-aminobenzol-3-suliosäure   <I>er-</I>  hältlich ist,

   in Gegenwart von Sauerstoff oder  Sauerstoff abgebenden Mitteln mit     1-p-Toluol-          sulfamino-4-amino-2-ohlorbenzol    kondensiert  und mit verseifenden Mitteln die     Aeidyl-          gruppe    abspaltet.

      <I>Beispiel:</I>    Die aus     3,0    Teilen     3-Sulfophenyl-2-naph#          tylamin    und<B>21,8</B> Teilen     1-Dimethylamino-          4-aminobenzol-3-sulfosäure    erhaltene     Isoros-          iridulin-1-12-disulfosäui-e    wird durch Behan  deln mit<B>30</B> Teilen     1-p-'Toluolsulfamino-4-          amino-2-chlorberizol    in Gegenwart von Sauer  stoff und durch Abspalten der     Acidylgruppe     mit verseifenden Mitteln in eine     Safranindi-          salfosäure    übergeführt.

   Der so erhaltene Farb  stoff färbt Wolle in saurem Bade blau.



  Additional patent to main patent no. <B> 107855. </B> Process for the preparation of a wool dye of the Safranin series. The main patent describes a process for the preparation of a wool dye of the Safranin series, according to which isorosindulin-1-12-disulfonic acid of the formula
EMI0001.0010
    condensed in the presence of oxygen or oxygen-releasing agents with 1-4-diamiiiobenzene-2-sLilfo,% ätire.



  A dye which has the same good properties as that described in the main patent is now obtained if the isorosindtilin-1-12-disulfonic acid is given by the formula
EMI0001.0016
    which is available from S-sulfophenyl-2-Y) aphtylamine and 1- dimethylamino-4-aminobenzene-3-sulfio acid,

   condensed in the presence of oxygen or oxygen-releasing agents with 1-p-toluenesulfamino-4-amino-2-chlorobenzene and splitting off the aeidyl group with saponifying agents.

      <I> Example: </I> The isoros acid obtained from 3.0 parts of 3-sulfophenyl-2-naphthylamine and <B> 21.8 </B> parts of 1-dimethylamino-4-aminobenzene-3-sulfonic acid iridulin-1-12-disulfosäui-e is prepared by treating with <B> 30 </B> parts of 1-p-'toluenesulfamino-4-amino-2-chlorberizole in the presence of oxygen and by splitting off the acidyl group with saponifying agents converted into a safranine disulfonic acid.

   The dye thus obtained dyes wool blue in an acid bath.
